Magnet Countersunk High Quality Permanent Magnet | Fullzen Technology

Short Description:

Neodymium countersunk magnets is one of the most common types of magnets in permanent magnets. N42 neodymium magnets are permanent magnets, which can be natural products, also known as natural magnets, or artificially manufactured (the strongest magnet is a NdFeB magnet). It has a wide hysteresis loop, high coercive force, and high remanence. A material that maintains a constant magnetic field once magnetized.

Also known as permanent magnet materials, hard magnetic materials. In the application, the permanent magnet works in the second quadrant demagnetization part of the magnetic return line after deep magnetic saturation and magnetization. Permanent magnets should have as high a coercivity Hc, remanence Br and maximum energy product (BH)m as possible to ensure the maximum storage of magnetic energy and stable magnetism. Our company Fullzen is a countersunk magnet factory in China, which can provide high-quality bulk countersunk neodymium magnets, please contact us for related business inquiries.

    Magnet Countersunk

    Rare earth permanent magnet material (NdFeB Nd2Fe14B):  Divided into the following three types according to the production process. Bonded NdFeB 

    ——Bonded NdFeB is a composite NdFeB permanent magnet made by uniformly mixing NdFeB powder with binders such as resin, plastic or low-melting point metal, and then compressing, extruding or injection molding. The product is formed once, without secondary processing, and can be directly made into various complex shapes. Bonded NdFeB is magnetic in all directions and can be processed into NdFeB compression molds and injection molds. High precision, excellent magnetic properties, good corrosion resistance, good temperature stability.

    Sintered NdFeB

    Sintered NdFeB permanent magnets are smelted after jet milling, with high coercive force and extremely high magnetic properties. The maximum magnetic energy product (BHmax) is 10 times higher than that of ferrite (Ferrite) above. Its own mechanical properties are also quite good, and it can cut and process different shapes and drill holes. High-performance products have a maximum operating temperature of up to 200°C.

    Due to its substance content, it is easy to cause corrosion, so the surface must be treated with different coatings according to different requirements. (such as galvanized, nickel, environmental protection zinc, environmental protection nickel, nickel copper nickel, environmental protection nickel copper nickel, etc.). Very hard and brittle, with high resistance to demagnetization, high cost/performance ratio, not suitable for high operating temperatures (>200°C).

    Injection NdFeB

    Extremely high precision, easy to make thin-walled rings or thin magnets with complex anisotropic shapes.

    Permanent magnets are widely used in various fields such as electronics, electricity, machinery, transportation, medical treatment and daily necessities.

    Magnetic Product Description:

    This neodymium magnetic disc has a diameter of 50mm and a height of 25mm. It has a magnetic flux reading of 4664 Gauss and a pull force of 68.22 kilos. 

    Uses For Our Strong Rare Earth Disc Magnets:

    Strong magnets, like this Rare Earth disc, project a powerful magnetic field that is capable of penetrating solid materials such as timber, glass or plastic. This ability has practical applications for tradespeople and engineers where strong magnets can be used to detect metal or become components in sensitive alarm systems and security locks.


    What is the countersunk magnet joint?

    The term "countersunk magnet joint" likely refers to the way countersunk magnets are used to create joints or connections in various applications. Countersunk magnets are often employed in pairs or sets to form joints that are secure, functional, and aesthetically pleasing.

    How to gauge countersunk magnet length?

    Gauging the length of a countersunk magnet involves measuring the distance from one end of the magnet to the other. Here's how to do it:

    1. Choose a Measuring Tool
    2. Position the Magnet
    3. Measure the Length
    4. Read the Measurement
    5. Record the Measurement
    6. Consider the Countersink Hole
    7. Compare with Specifications
    What material does countersunk magnet ?

    Countersunk magnets can be made from various magnetic materials, each with its own properties and characteristics. The choice of material depends on the specific requirements of the application. Some common materials used for countersunk magnets include:

    1. Neodymium (NdFeB) Magnets
    2. Ceramic (Ferrite) Magnets
    3. Alnico Magnets
    4. Flexible Magnets
